Title: Heatdevelopable photosensitive material having improved minimum density and physical property
Inventor: IWAGAKI MASARU
IPC: G03C1/498
Filed: 1986-10-09
Abstract: PURPOSE:To obtain the low min. density of the titled material, without reducing the max. density by incorporating an aqueous polyester to a photosensitive layer or a non-photosensitive layer. CONSTITUTION:The photosensitive layer or the non-photosensitive layer contains the aqueous polyester. The used aqueous polyester is obtained by effecting an emulsion polymerization of a high polymer compd. which is produced by effecting an esterification of a polybasic acid (such as phthalic acid etc.) and a polyhydric alcohol (such as glycol, etc.) to form an emulsion, or by introducing a hydrophilic group to the high polymer compd. or by combining the two former methods. The compounding amount of the aqueous polyester is 0.05-20g, preferably 0.2-10g per 1m<2> of the heatdevelopable photosensitive material. Thus, the titled material is improved in the min. density, without reducing the max. density, and has improved film property (such as a generation of crack).

Title: Continuous casting method of molten metal
Inventor: JIYANNFURANSOWA NOBUIRU
IPC: B22D11/07
Filed: 1988-09-26
Abstract: PURPOSE: To improve the surface quality of product and to improve the productivity of equipment by executing casting by using a lubricating material of a spherical form having a diameter size not exceeding a specific value and consisting of glass. CONSTITUTION: The lubricating material to be used for continuous casting comprises the glass or sodium calcium glass and is formed to the spherical ball form of the diameter size not exceeding 1.5 mm. Further, the softening initiation temp. of the lubricating material is so set as to be kept within a range of about 400 to 800 deg.C. When the lubricating material balls are injected between the inside walls of a casting mold and molten metal via conduits in the inside walls of a casting mold, the lubricating material softens and melts at the temp. at the time of casting and exhibits a sufficiently low viscosity, thereby closing the spacings between the product surface and the inside walls of the casting mold in a state of a good flow property.  As a result, the quality of the product surface is improved and the productivity of the equipment is improved without the damage of the equipment on account of the softening and melting of the spherical glass balls.
